head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Stylish JRPG where phantom thieves steal hearts on a tightly optimized school calendar.

Optimization · Pure Optimization
A solvable type-matchup system wrapped in collection and light RNG.

Pokémon Blue Version leans a little harder on reads, though the gap is small.

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.

Confidant calendar routing and baton-pass weakness chains
Pokémon Blue Version
Type chart and team building make the campaign solvable
